Current Status of Cosmological Models with Mixed Dark Matter
An analysis of cosmological mixed dark matter models in spatially flat Friedmann Universe with zero Λterm is presented. We argue that the introduction of cosmic gravity waves helps to satisfy observational constraints. The number of parameters is equal to 5, they are (1) σ8, the dispersion of the mass fluctuations in the sphere with radius 8hMpc, (2) n, the slope of the density perturbation spe...
متن کاملCold dark matter models with a cosmological constant
We use linear and quasi-linear perturbation theory to analyse cold dark matter models of structure formation in spatially flat models with a cosmological constant. Both a tilted spectrum of density perturbations and a significant gravitational wave contribution to the microwave anisotropy are allowed as possibilities. We provide normalizations of the models to microwave anisotropies, as given b...
متن کاملSimplified models of mixed dark matter
We explore simplified models of mixed dark matter (DM), defined here to be a stable relic composed of a singlet and an electroweak charged state. Our setup describes a broad spectrum of thermal DM candidates that can naturally accommodate the observed DM abundance but are subject to substantial constraints from current and upcoming direct detection experiments. We identify “blind spots” at whic...
متن کاملInflation and Mixed Dark Matter Models
Recent large scale structure observations, including COBE, have prompted many authors to discuss modifications of the standard Cold Dark Matter model. Two of these, a tilted spectrum and a gravitational wave contribution to COBE, are at some level demanded by theory under the usual assumption that inflation generates the primeval perturbations. The third, whose motivation comes by contrast from...
متن کاملSupersymmetric dark matter with a cosmological constant
Recent measurements of cosmological parameters from the microwave background radiation, type Ia supernovae, and the age of globular clusters help determine the relic matter density in the universe. It is first shown with mild cosmological assumptions that the relic matter density satisfies ΩMh 2 < 0.6 independent of the cosmological constant and independent of the SNIa data. Including the SNIa ...
